This is just typical... I got impatient waiting for my Sena case to arrive... so I ordered me a black Piel Frama. Just as I was about to cancel my Sena case order, I get an email "We have dispatched your order" from Sena... Oh well, at least I'll be able to draw up a comparison for you all. I have the Piel Frama right now (just arrived today). The leather really is high grade - very soft and stinks of good quality leather

. The manufacturing quality is very good... except for a few scuffs where the leather has been rubbed against a surface whilst being stitched together
Its a nice, snug fit. It does add quite a bit of bulk to the device, but its worth it for the protection. It may be worth inserting something stiff (maybe just cardboard) into the flip cover, because with nothing in there... there's very little protection for the screen.
Theres no chance of putting this in the sync cradle with the case on, but you could use a travel USB sync cable.
One thing that worries me about the Piel Frama is the very thin section around the stylus silo... it seems that it could easily rip, or maybe if the leather begins to crack it could fatigue. Other than that, I'm very happy with it indeed!
